§ 10202 Confirmatory Memoranda Terms
This law says that if people write down their agreement, they can't later say there was a different deal. But they can add details if it makes sense with how they usually do things.
You and your friend write down that you'll sell your bike for $100.
Later, your friend can't say you also promised to give them a free helmet unless you both usually do things like that when selling bikes.
